Wafer-scale graphene technology and GHz nanoelectronics (invited)

Graphene nanoelectronics have made significant progress over the past five years particularly in material synthesis, device physics, and circuit applications. The high achievable mobilities at room temperature coupled with its high linearity (or invariant-transconductance) [1], and transit frequencies that exceed conventional solid-state transistors (see Fig. 1) make it ideally suited for GHz and THz analog electronics [2]. However, there are several challenges that need to be addressed for graphene to be a next-generation technology. In this light, we report significant experimental and theoretical progress to address these challenges in three essential areas namely wafer-scale graphene synthesis, compact device modeling, and GHz analog circuits.
